GX product family

Introduction

A Venus-device is the communication-centre of your installation. It connects the components together and ensures they are working in harmony. Monitoring of live data, and changing settings is performed via our free-to-use Victron Remote Management Portal (VRM).

The GX product family consists of the different Venus-devices; each suitable for their own best type of system. Besides that there are accessories which can be used to extend the functionality.

The Venus devices are:

Color Control GX
Venus GX
Octo GX - The Octo GX is the best fit for installations that have many MPPT Solar Chargers, as it has 10 VE.Direct ports
CANvu GX - The CANvu GX is best used when IP67 rating is a must.

Available accessories

GX GSM - A cellular modem, connects to Venus-device via USB and takes a simcard
WiFi USB sticks
Energy Meters - Measures PV Inverter Output for types of PV Inverters that cannot be read-out directly. And used as a grid meter in an Energy Storage System (ESS).
VE.Can resistive tank sender adapter The VE.Can resistive tank sender adapter allows a standard resistive tank level sender to connect to the Venus-device.

Notes:

The maximum number of VE.Direct devices: on a CCGX is 5 (2 normal and 3 via USB). On a Venus GX is 6 (2 normal and 4 via USB). On a Octo GX is 10 (10 normal, no USB). VE.Direct ports on a Venus-device are isolated.
Though the CCGX has no built-in WiFi it can easily be added by attaching a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details.
The built-in WiFi in the Venus GX has a very low signal strength - unfortunately. The strength is sufficient for connecting to a phone, tablet or laptop in order to access setup and monitoring. But to connect the Venus GX to the internet either use the built-in Ethernet port or add a USB-WiFi dongle. See CCGX Manual, section 1.4.2 for details. Make sure the Venus GX is running v2.06 or later - the first shipment of Venus GX units ran v2.05.
Though the hardware of the Venus GX and Octo GX have a Bluetooth Smart chipset inside; it doesn't work properly and they are unfixable. Bluetooth Smart for Venus-devices is coming but not using those built-in chipsets.
Larger SD memory cards (SDXC) are not supported. SD cards can be used for two purposes:
1. Logging data, see this section in the ccgx manual for details.
2. Updating firmware, see this section in the ccgx manual for detials.
The second CANbus port is accessible via the GND, CAN-H and CAN-L terminals. Note that the port is not Isolated. See Settings → Services for configuring that port.
The programmable relay can be set to act as an alarm relay, automatic genset start stop, or an on/off switch, and is controlled via the GUI and/or ModbusTCP.
In the Venus GX hardware there are two relays - at present only one of them is available for use.
The tank level inputs are resistive and should be connected to a resistive tank sender. Victron does not supply tank senders. The tank level ports can each be configured to work with either European (0 - 180 Ohm); or US tank senders (240 - 30 Ohm).
The Venus GX has two temperature terminals which can be used to measure & monitor all kinds of temperature-inputs. Temperature senders are not included. The required sensor is ASS000001000 - Temperature Sensor QUA/PMP/Venus GX. (Note that this is not the same as the BMV temperature accessory.)
Octo GX comes with a small Wifi antenna. It is possible to replace it by any other Wifi antenna having a RP-SMA connector.
